Funding Amount

Summary
We have shown that a protein called Abca12 can control the transport of lipids in our bodies. If the function of this gene is attenuated both human and mice develop severe skin disease. Our preliminary results indicate the Abca12 protein regulates cholesterol transport in particular, and this grant will investigate how this might affect normal skin function and contribute to the heart disease atherosclerosis, one of the most common causes of death in the western world.
Topical Drug Delivery Based On Porous Silicon Nanoneedles

Summary
There are currently a number of new drugs that can only be administered through the skin via hypodermic needles, which is costly, invasive and carries the risk of infection spread. This project proposes to develop an alternative strategy based on skin patches covered in millions of microscopic porous needles. These needles are able to puncture the skin painlessly to provide rapid and minimally-invasive administration of drugs for treatment of skin diseases, such as melanoma or psoriasis.
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier

Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.
Defects In Epidermal Morphogenesis In Grainyhead-like Gene Deficient Mice

Summary
The cells of the skin play an essential role in the development of the mammalian embryo. They are critical for forming a protective barrier against infection and external toxins, for preventing excess fluid loss, for repair of defects and wounds , and for the generation of hair. Our laboratory has identified a family of genes that are critical for these processes. The aim of this study is to determine the relationship between these genes to further our understanding of the skin and its functions
Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. Most bacterial and viral pathogens enter the body via mucosal tissues. We have recently demonstrated that mucin proteins are a vital component of initial defence against mucosal pathogens. Defects in these proteins probably predispose individuals to common chronic infective and inflammatory diseases.

Most bacterial and viral pathogens enter the body via mucosal tissues. We have recently demonstrated that mucin proteins are a vital component of initial defence against mucosal pathogens. Defects in these proteins probably predispose individuals to common chronic infective and inflammatory diseases. The proposed research aims to explore the mechanims by which mucins protect from infection, with a focus on the gastrointestinal tract. Gastrointestinal infections remain one of the major causes of mortality in children in undeveloped countries. We believe that these proteins are a critical hereto unrecognised element of immunity and that the proposed studies will have broad significance for treatment and prevention of infection. Additionally, understanding the function of mucins could lead to the development of new drugs to treat epithelial inflammation such as that seen in inflammatory bowel diseases and respiratory diseases such as asthma and cystic fibrosis.Read moreRead less
Simulating And Stimulating The Blood-Brain-Barrier: A Platform For Investigating Non-pharmaceutical Alzheimer's Therapy

Funding Amount
$680,758.00
Summary
Alzheimer's disease is a looming public health threat worldwide. Despite the widespread acknowledgement of this issue, there are a lack of effective drugs that can slow disease progression. This project aims to investigate a new class of non-pharmaceutical treatment methods based on controlled acoustic, electrical and optical stimulation methods to treat and reverse the base causes of Alzheimer's disease.
CD4+CD8β+ Double-positive T-cell Regulation Of CD8 T-cell Responses

Summary
T-cells are a type of white blood cell that play an essential role in the immune system. CD4+CD8+ Double-Positive (DP) T-cells are a rare and poorly defined T-cell subset associated with skin disease - however their function and subsequently their contribution to disease is not known. Our preliminary data suggest that these DP cells may regulate the function of other immune populations in the skin. This project aims to deliver key insights into DP cells and their role in skin disease.
Modulating Inflammation As A Therapy For Harlequin Ichthyosis

Funding Amount
$718,739.00
Summary
Harlequin Ichthyosis is a severe inherited skin disease caused by mutations in a protein which regulates how skin cells control their levels of lipids. Treatments for this disease are limited and do little to improve patients condition. We believe we have found a new way to treat this condition by altering tissue inflammation. This grant will undertake important experiments aimed at developing new therapies for this currently incurable disease.
Restoration Of Cognitive Deficits Induced By Diabetes Through The Modulation Of Cerebrovascular Integrity

Funding Amount

Summary
Diabetes is a known risk factor for the development of dementia. However the details of this association have not been known. Recent evidence consistently shows that the integrity of blood vessels in the brain may be central to the onset of dementia, and consistently, damaged brain blood vessels are often reported in diabetic patients and animal models. This project is the first to target in restoring the integrity of those brain blood vessels in order to reverse diabetes-associated dementia.
